underscore prefix

[mike parr]

A few times when looking at code on the net I have seen objects,
variables etc prefixed by an underscore. But I've never seen any
explanation for the reason for this. What is the reason for doing this?

Thanks,

Mike

This is olb naming convention for private variables. In new MS naming
convention you should use m_ as prefix for private members

I think the guidlines actually discourage use of m_ when it says "Do
not apply a prefix to field names or static field names."

Nothing magical about it; it's just one of many naming conventions for
private class members. I think the underscore prefix is favored by C++
coders.

I think prefixing any variable in a strongly typed environment simply adds
clutter. I find the convention of capitalizing public members but not
private is much more elegant. Just my opinion.

Hmm...I have always been in the opinion that whenever we have an exposed

member like a public variable or property etc, we should avoid Hungarian
Notation and prefixes of any type. But for private entities, I would use m_
or a prefix...
